Puquios are ancient systems of subterranean aqueducts which allow water to be transported over long distances in hot dry climates without loss of much of the water to evaporation. Puquios are found in the coastal deserts of southern Peru, especially in the Nazca region, and northern Chile. Forty-three puquios in the Nazca region were still in use in the early 21st century and relied upon to bring fresh water for irrigation and domestic use into desert settlements. The origin and dating of the Nazca puquios is disputed, although some archaeologists have estimated that their construction began about 500 CE by indigenous people of the Nazca culture.

The Nazca culture was the archaeological culture that flourished from c. 100 BC to 800 AD beside the arid, southern coast of Peru in the river valleys of the Rio Grande de Nazca drainage and the Ica Valley. Strongly influenced by the preceding Paracas culture, which was known for extremely complex textiles, the Nazca produced an array of crafts and technologies such as ceramics, textiles, and geoglyphs.
